Application filed December 28, 1904. Serial No- 238,598.

To all whom it may concern:

Be it known that we, J OHN W. KERR- and LUcIos A. HINE, citizens of theUnited States, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inLamp-Holders, of which the following is a specifica- Our inventionrelates to holders or brackets for lamps of the portable type, and whilethe same is more particularly designed and intended for such particularcharacter of lamps as commonly used on automobiles, yet its use is notlimited thereto. On the contrary, we contemplate using our inventionWherever applicable and in connection with all characters of portablelamps, Wherever used.

The object of our invention is to provide a lamp holder or bracket whichshall be universal nbt only in respect to different sizes of lampsbut'also in respect to positions or inclination, with the result thatone holder may be accommodated to any particular size or character oflamp, and may also be adjusted to cast or direct the beam of light inany direction and at any angle.

The various features of novelty and advantage resulting from the use ofour construction of lamp holder will be apparent from the descriptionhereinafter given.

In the drawings, Figure l is side elevation of our lamp holder carryingan acetylene gas lamp of well known construction; Fig. 2 a plan view ofthe lamp holder; Fig. 3 a section on the line 33 of Fig. 2; Fig. 4 asection on the line 4l of Fig. 2;v Fig. 5 a perspective of a modifiedform of construction of the holder;

and Figs. 6 and 7 detail views thereof.

Referring first to the form of holder illustrated in Figs. 1 to 4, suchholder comprises a post 1, which is adapted to be secured to the vehicleor other point ofsupport and in which the fork or holder proper isniounted univorsally in the present instance. This fork as shownconsists of two members or prongs 2 and 3, adjustable with respect toeach other, with the result that such prongs may be moved toward andaway from each other in arcs of a circle and different sizes ofcharactors of lamps thereby accommodated.

In the present instance the lamp holder proper, which is substantiallyformed as two prongs with 'a cross-piece at the lower end, has a balland socket connection with the post. the ball being arranged on theorosspiece of the fork or holder proper and the same being splithorizontally so as to form two sub stantially semi-spherical portions orhalves2 and 3, which are fitted together so as to constitute a singleball movable in a socket as hereinafter described. This ball is arrangedat the middle of the cross bar of the fork and the halves thereofconstitute the meeting ends of the two members or prongs ofthe fork.Moreover, these halves of the ball are pivoted on a common axis, and inthe present instance are pressed upon each other by means of a pin andsocket connection, one of the half balls, say the one marked 2, having acontral dowel pin or pivot 2 arranged to fit into acorresponding socketin the other half ball 3.

The fork with its ball bearing is mounted in a socket at the upper endof the post, the construction of the sogket being such that the ball maybe clamped to hold the fork in any position to which it may have beenadjusted. For the purpose the post has a horizontal flange or lateralextension 4 at its upper end, to which is secured by means of bolts 5and (S a. clamping plate It will be understood that by screwing down thebolts 5 and 6 the fork may be firmly clamped to the post in any adjustedpositiomwhich adjustment is an universal one because of the ball andsocket connection between such parts, with the result that the lamp,such as the lamp 8, whose fastening lugs or sleeves 9 receive the prongsof the fork, may cast its light inany direction, as determined by theoperator.

By preference the bolt 5 is screwed down to a predetermined position andthereafter the clampingjand unclainping is accomplished simply by theother bolt 6, in which event such latter bolt is provided with a Wrench10 secured thereto ready for instant use. To prevent loosening of thebolts, which is liable to occur from the vibration of the machine orvehicle, we provide the bolts with spiral springs 11, coiled around thebolts and exerting constant tension against the clamping plate 7.Furthermore, for convenient manipulation of the lamp, especially thesearchlight type of lamp which is mounted in automobiles for instant andeasy reach of the operator, we provide a Vshap ed liandle 12, whosesimilar arms or bifurcations terminate in eyes 12 adapted to slip overthe prongs of the fork or holder to a position below the lamp, asclearly indicated in Fig. 1.

By simply loosening the bolt 6, the holder with its lamp may be turnedto any position whatsoever; both horizontally and vertically, orintermediate, and preferably through the medium of the handle, and maybe secured to any adjusted position by tightening up such bolt. Or, ifthe lamp is a searchlight, the bolt B'may be left loose and the lampthen turned by the handle 12 Referring next to the modified iormofconstruction v illustrated in Figs. 5,6 and 7, the holder there shownembodies many of the features and principles illustrated and describedin the first form of holder, withthe exception that the adjustment ofthefork as an entirety is not universal as in the first form, theadjustment of the fork in the modified form beingin one plane only. Asshown,'this modified form of holder comprises a post 13 and a. forkconsisting of-two members 14 and 15, formed in two parts mounted on aconiinon axis at their meeting. ends and adjustable with resp'ectto eachother. These meeting ends are flattened and made in fork maybe adjustedwith respect to each other, as for instance in Fig. 7 the dotted linesillustrate the position.

of suclijineinbers or prongs adjusted for a. smaller size or characterof lamp. ll'ioreover, without changing the distance between the ends ofthe members of the fork, the entire fork-maybe adjusted in a horizontalplane.

By preference the upper end of the post 13 and the inner end of one ofthe members of the fork may be provided with engaging ratchet surfaces19, with the result that one of the members may be secured positively tothe post against any possibility of relative movement.

It is unnccessar to provide the other member of the fork with such meansfor positive adjustment or holding, inasmuch as the lamp itself" wouldprevent any spreading or contracting of the hold er.
